Hey @david_vanderson, check out this thread here for some related information: How to anonymously initialize a slice?
In short, you cannot make a literal mutable. The thing that assigns from a literal (the copy) can be mutable but the literal itself is not. Because of that, you’re basically going to initialize some memory (like you do on the first line) and then grab a slice to that memory (second line).
If you point directly at the literal, you need to have a constant pointer (non-mutable).
